Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibition of fungal cell mitosis by binding to microtubules, disrupting spindle formation and nuclear division.
Inhibits fungal cytochrome P450 (CYP450)-dependent lanosterol 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
125 mg orally once daily with a high-fat meal for 7 days, then 125 mg every other day for 7 days (total 13 doses).
200 mg orally twice daily for 3-7 days; for onychomycosis: 200 mg orally once daily for 12 weeks.

Terminal half-life approximately 9.5 hours; may be prolonged in liver disease.
The terminal elimination half-life of itraconazole ranges from 21 to 35 hours for single doses, increasing to approximately 34 to 42 hours at steady state. The half-life of the active metabolite, hydroxyitraconazole, is similar. This long half-life allows for once-daily or twice-daily dosing in most indications.
Primarily hepatic metabolism; <1% excreted unchanged in urine; metabolites excreted in bile and feces.
Itraconazole is extensively metabolized in the liver via CYP3A4 to active metabolites, including hydroxyitraconazole. The parent drug and metabolites are primarily excreted in feces (approximately 54%) and urine (approximately 35%), with less than 1% of the dose excreted unchanged in urine.
